Sublist3r2 is an improved and bug-free working version of Sublist3r, the original subdomains enumeration tool but with a much faster bruteforcing routine. It now uses aiodnsbrute instead of subbrute and is capable of bruteforcing 150k subdomains within 15 minutes (at default thread count of 7000).
Sublist3r is a python tool designed to enumerate subdomains of websites using OSINT. It helps penetration testers and bug hunters collect and gather subdomains for the domain they are targeting. Sublist3r enumerates subdomains using many search engines such as Google, Yahoo, Bing, Baidu and Ask. Sublist3r also enumerates subdomains using Netcraft, Virustotal, ThreatCrowd, DNSdumpster and ReverseDNS. (from original author page) "
Sublist3r2 currently supports python3 on linux dists. Python3.6+ is the recommended version.
Other operating systems (macos, windows) will be supported in later releases.
Sublist3r2 depends on the requests, dnspython , argparse and aiodnsbrute python modules.
Install Sublist3r and its dependencies, inside a python3 virtual env as detailed in installation steps below, in order to avoid non-tool specific python related errors that normally result from broken dependencies when user installs several dependency-conflicting python tools under the system-wide python installation.
Any issues raised due to inappropriate user installation will be closed to allow focus on resolving real bugs and implementing new features
The installation steps assume you will keep your python virtual envs in a folder called environments under your home directory directory:
1- $ git clone https://github.com/RoninNakomoto/Sublist3r2.git // Download tool from github
2- $ python3 -m venv ~/environments/sublist3r // create a python version 3 virtual environment for sublist3r
3- $ source ~/environments/sublist3r/bin/activate // activate sublist3r python environment.
4- $ python -m pip install --upgrade pip // update pip inside virtual env.
5- $ cd ~/sublist3r/ // switch to your sublist3r download folder.
6- $ pip install -r requirements.txt // install sublist3r module dependencies.
7- $ python sublist3r2.py -d domain.com // run sublist3r.py from within activated environment
8- $ deactivate // deactivate environment once done runnning the script.
note: do not use sudo. **Activate/deactivate virtual env. before/after each use**

- To list all the basic options and switches use -h switch:
./sublist3r2.py -h
- To perform basic enumeration of specified domain:
./sublist3r2.py -d example.com
- To check and filter subdomains for results with open ports 80 and 443 :
./sublist3r2.py -d example.com -p 80,443
- To enumerate subdomains of specific domain and show the results in realtime:
./sublist3r2.py -v -d example.com
- To enable bruteforce mode against specified domain:
./sublist3r2.py -b -d example.com
- To enumerate subdomains and use specific engines such as Google, Yahoo and Virustotal engines
./sublist3r2.py -e google,yahoo,virustotal -d example.com
